1 Period Date LAB : PAPER PET GENETICS 1. Given the list of characteristics below, you will create an imaginary pet and then breed it to review the concepts of genetics. Your pet will have the following possible characteristics: Characteristic Gender male (hat) Trait () or female (hair bow) Skin color green or orange Eyes round or square Nose triangle or oval Teeth pointed or square 2. The genetics of these characteristics and their traits are summarized in the table below: Characteristic Trait (Phenotype) Genotype Gender male XY female Skin color green FF or Ff orange Eyes round EE or Ee square Nose triangle NN or Nn oval nn Teeth pointed TT or Tt square XX ff ee tt 3. Work in teams of two. Each person needs to design her or his own pet for the original parents. You will get to mate them later. Determine the for each of the characteristics for your pet in the following manner: To simulate the random way chromosomes are divided up during meiosis into egg and sperm, you will flip a coin to determine what kind of allele for each trait your pet inherits from each parent. THE RULES: HEADS = Dominant allele TAILS = Recessive allele 1 of 6

2 4. Each of you will be filling out your chart SEPARATELY. Each of you will have DIFFERENT information. One of you will be the male pet of the pair and one of you will end up being the female pet of the breeding pair. Just flip a coin to decide this. But for all other traits you must use the coin flipping rules from the previous page. Flip the coin for each allele for each trait in the chart below to determine the and of your new pet, and then write it in the chart. Characteristic Allele from Pet s Dad Allele from Pet s Mom Genotype of Pet Phenotype of New Pet Skin color Eyes Nose Teeth Gender 5. Place the information from your chart on index cards, so we can start making a poster of your new pet family. 6. Follow this template for the final poster: Phenotype NAME Genotype Phenotype NAME Genotype NAME NAME NAME NAME 2 of 6

3 7. Your pet now mates with your partner s paper pet. There are four offspring in the new family. For each characteristic, use a Punnett square on the next page to determine all of the possible s of the offspring. 8. To choose which one of the squares in your Punnett square is the trait for each of your pet s four offspring use this coin toss system: Toss a coin a first time: If heads, the offspring is in the top row of the Punnett square. If tails, the offspring is in the bottom row of the Punnett square. Toss a coin a second time: If heads, the offspring is on the left side of that row in the Punnett square. If tails, the offspring is on the right side of that row in the Punnett square. 9. Summarize the traits for each pet offspring in the chart below. You will repeat this coin toss method 4 times: Once for each of the paper pet s four offspring in the new family. Gender (Sex) Skin color Eyes Nose Teeth Offspring 1 Offspring 2 Offspring 3 Offspring Use colored paper, scissors, and glue to create the parents and four offspring in your paper pet s new family. Glue the index card with the parent s information to the poster as well. Name each pet and give the whole family a family name. 3 of 6

5 QUESTIONS 1. Explain what is meant by the term, homozygous dominant. 2. Explain what is meant by the term, heterozygous. 3. Explain what is meant by the term, dominant. 4. Explain what is meant by the term, recessive. 5. Explain what an individual would have to have genetically to show the recessive trait. 6. Do all your pet s offspring look the same? If no, then explain why they look different. 5 of 6

6 7. Using a Punnett square and an explanation describe if a square-eyed pet mates with another square-eyed pet, can they have any round-eyed offspring. 8. Using a Punnett square and an explanation describe if an orange pet mates with another orange pet, can they have any green offspring. 9. Using a Punnett square and an explanation describe if a green pet mates with an orange pet, can they have any orange offspring. 10. Why did we use coin-flipping as a method to choose traits for the parent pets and the offspring pets? 11. Explain how coin-flipping simulates the events of meiosis and the production of sperm or eggs. 6 of 6
